A lady is driving a car clockwise around a circular track of radius 20m. It takes her 105 s to complete one lap around the track. Find the driver’s speed, and centripetal acceleration.

that would be b i just took the test : )

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

0.11 m/s and 0.28 m/s should be correct

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
